"I'he subj'eot of this invention" is. t a novel: 7 and improved dividing orspattern f ormingstrip such as is used "for wait and" fl'oor structures, for I instance; terrazzo floors;- where:avariegateddesig-n 6 is=to be-exposed on-thei finished structure. Forconvenience;'therefore, the new= strip will. be re-v ferred to hereinafter as a'terrazo strip and: the advantages-of the-same will be described in con nectionwith the laying of terrazzo floors.

A terrazzo strip, as is well known-in the art, is laid duringethelaying of the floor, and forms an inbuilt part of the completed floor.

One of the objects of the present invention: is ta provide a terrazzo; strip, which may be cheaply formed, as-by a stampingaoperation, for instance out of thinsh'eetbrass and'whicl'n whiie having po'rtionsdisplaced from the general planeof the strip; for inter -locking 1 with the plastic material one-""01 'both sides-of the ship, will present these displaced portions otherwisev than as tabs or -tongues. v

Another object is to provide a terrazzo strip of great-"strength: andi'rigidity and small. cost,

and at the same time one incorporating portions trom the general plane of the strip, for participating in the interlocking feature aforesaid.

Another object is to provide a terrazzo strip as above, and one wherein said displaced portions are nonuniplanar projections, preferably formed by stretching as well as displacing the strip material.

Various other objects and advantages of the invention than those hereinabove mentioned will be specifically pointed out or will be apparent hereinafter in the course of the below detailed description of the forms of the invention shown, in the accompanying drawing, as preferred ones of the various possible embodiments of the invention; it being understood, naturally, that such forms are merely illustrative of some of the many possible combinations and arrangements of parts well calculated to attain the objects of the of rounded, upwardly tapering projections 7;

formed by pressing out and stretching the strip material.

It is also to be understood that the language contained in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.

I claim: 7

1. A strip for the purpose described having pocket forming portions projecting from the sides thereof with the edges of the pockets all in a single plane at right angles to the strip and spaced from one of the longitudinal edges of the strip.

2. A strip for the purpose described having segmento-conoidal portions struck out from the body of the strip and each having an arcuate edge portion free from the body of the strip whereby said portions form pockets open at one end, said arcuate edge portions all lying in a common plane at right angles to the body of the strip and spaced from the edge towards which the pockets face.

3. A strip for the purpose described, having an uninterrupted straight longitudinal upper edge and having segmento-conoidal portions struck out from the body of the strip forming in each instance a depression at the side and extending transversely of the strip, one end and the 1 body of each depression being continuous with the strip, and the other end of each depression separate from the strip, the edges constituting said opposite ends of each depression being all, and each in its entirety, in a plane parallel to and spaced from the said longitudinal edge of the strip, and the first named endof the depression being adjacent the other longitudinal edge of the strip.

4. A strip for the purpose described, having n uninterrupted straight longitudinal upper edge and having segmento-conoidal portions "struck out from the body of the strip formingincach instance a depression at the side and extending transversely of the strip, one end and the body of 5 each depression being continuous with the strip, and the other end of each depression separate from the strip, the edges constituting said opposite ends of each depression being all, and each in its entirety, in a plane parallel to and spaced from the said longitudinal edge of the strip, and the first named end of the depression being adjacent the other longitudinal edge of the strip," one of such depressions being located at one side of the strip, and another of such 'depressions being located at the'opposite side of the strip. 7 i I 5. A strip for the purpose described, having .an uninterrupted straight longitudinal 'upperedge and having segmento-conoidal portions struck 1',9ss,2ec o nally of the strip and extending alternately at opposite sides thereof. I

6. A dividing strip having projecting laterally therefrom a plurality of scoop-shaped portions spaced longitudinally along the strip, each of said scooped-shaped. portions having a mouth directed toward. and spaced from a longitudinal edge of the strip, the mouth being defined by a free edge spaced laterally from the plane of the strip, substantially all of the remaining periphery of the scoop-shaped portionbeing attached to the strip. V g

'l. A dividing strip having projecting from the opposite sides thereof a plurality of scoopsha'ped portions spaced longitudinally along the strip, each ofsaid scoop-shaped portions having a mouth directed toward and spaced from a longitudinal edge .of the strip, the mouthbeing defined by a free edge spaced laterally from the plane of the strip, substantially all of the remaining periphery; of,-the scoop-shaped portion being attached to thestrip. v

-8. A dividing striphaving projecting laterally therefrom a plurality of; scoop-shaped portions spaced longitudinally along the strip, each,,of said scoop-shaped portions havinga mouth directed toward and spaced from the bottom longitudinal edge of the strip, the mouth, being deflnedbya free edge spaced laterallyfrqmthe plane of the strip, substantially all of the remaining periphery of the scoop-shapedportion; being attached to the strip. V

9. A terrazzo strip comprising a strip of metal havinga straight uninterrupted upper edge, the metal ofthe stripbeing cut at successiveloca+ tions and portions of thefmetal adjacent to the cuts being stretched laterally into'scoop-shaped portions, each of said scoop-shaped portions having a mouth defined by a free ,edge which curves laterally away from the plane of the stripand then back to the plane of the strip, substantial: ly all of the ,remaining -peripherygof the ,scoopshaped portion being integral with the strip a
